Answer:
$3456
Step-by-step explanation:
We are given;
- Money deposited (principle) as $2,700
- Rate of interest is 3.5%
- Time is 8 years
We are required to determine the amount that will remain after 8 years
- We first need to determine the interest earned after eight years using the simple interest formula.
Simple interest = (Principle × rate × interest periods) ÷ 100
Therefore;
Interest = ($2,700 × 3.5% × 8 yrs)÷ 100
= $756
Then determine the amount after 8 years
Amount = Principle + Interest
Therefore;
Amount = $2700 + $756
= $3,456
Therefore, the money in the account after 8 years is $3456
Answer:
an hour
Step-by-step explanation:
80 divided by 80... 1.
We have 60 gallons of 20% antifreeze.
How much 70% antifreeze do we add to get 60% antifreeze?
We'll make "x" the gallons of 70% we must add.
.20 * 60 + .70 x = .60 * (60 + x)
12 + .70x = 36 + .60x
.10x = 24
x = 240 gallons of 70% antifreeze.
